Find the equation of the circle whose center and radius are given.

center (5,6), radius = 3

(x - 5) ² + (y - 6) ² = 9

Step-by-step explanation:

The equation of a circle in standard form is

(x - h) ² + (y - k) ² = r²

where (h, k) are the coordinates of the centre and r is the radius

Here (h, k) = (5, 6) and r = 3, thus

(x - 5) ² + (y - 6) ² = 9 ← equation of circle
